To all whom it may concern:

Be it known thatI, ALBERT FRANZHEIN- RICH HAMANN, a subject of the German Emperor, and resident of Hamburg7 Germany, have invented certain new and useful Improvements in Casements or Folding Windows7 of which the following is a specification.

This invention relates to improvements in easements or folding windows having a easement or easements adapted to be turned or swung in both directions, that is to say, inwardly and outwardly. On account of its novel arrangement, actuated in an extremely simple and convenient manner not only is a better and more complete closure against drafts and water obtainedby the improved construction, but the easements or valves when turned or folded inward, may be also brought together into position to allow of ventilation of the room.

The window is characterized in that besides the well known intermediate vertically hanging stiles hinged to the easement frame and carrying the easements, horizontal upper and'lower beads or rabbet bars are hinged to the easement frame in such manner that they may be folded or turned between the mo'vable stiles so as to clamp the latter and form in conjunction therewith the complete intermediate abutment frame for the easements. The horizontal bars may also be 'fixed to the stiles by suitable means during the ordinary use of the easements.

By the arrangement of the four stiles hinged to the window frame a special fastening device for the two vertical stiles carrying the wings is dispensed with, as these latter stiles are held in their proper position against the window frame by the lower and upper horizontal stiles or bars fitting with the end faces snugly between the vertical stiles and pressing them tightly against the window frame. In order to fold or turn the easements inwardly, it is only necessary to fold back or inward the upper and lower stiles or bars whereon the easements and the vertical strips carrying them can be turned inward.

In the accompanying drawing Figure 1 is an elevation of the improved folding window seen from inside; in this position of the parts the wings or easements are adapted to be folded outwardly. Fig. 2 is a vertical and Fig. 3 is a horizontal section. Fig. 4 is a horizontal section with inwardly turned wings or easements brought together for the purpose of ventilation.

On the inside of the window frame a vertical stiles b of known form are arranged to fold inwardly by means of hinges c and horizontal bars d (above and below) by means of the hinges c. The stiles or bars b and d form when folded against the window frame a in the manner shown in Figs. 2 and 3, a continuation of such frame and at the same time the tongue for the easements or valves f (Figs. 2 and 3). The stiles o are secured in the position shown in Figs. 1 and 3 and held tightly against the inner wall of the window frame a by the bars d engaging between the stiles t and exactly fitting the same. The bars d are held in position by the friction between their ends and the stiles l). If desired they may moreover be secured in this position by sliding bolts g arranged at the ends of the bars d and engaging suitable recesses in the stiles b. To obtain a tight closure between the stiles or bars I), d and the window frame a, the contacting surfaces are grooved or rabbeted to engage or interfit with one another.

To the outside 'faces of the stiles b the window easements j' are rotatably attached by means of hinges 7L; the easements f may be provided with suitable closing means (not shown) engaging in the bars d and pressing the easements against the stiles or bars b and d.

In order to allow of inward turning of the easements or wings f the bars d are folded inward, as shown in dotted lines in Fig. 2 and in full lines in Fig. 4, whereby the stiles b are released so that the easements and the thus freed stiles b may be swung or turned inward. Vhen in this inward turned position of the stiles?) the casementsf are closed, so that the edges of the easement frames meet in the center, as is shown in Fig. 4, the free window aperture remains closed, but an upper and lower slot like opening is left for ventilation of the room between the closed easements and the 'window frame. In this position of the easements the outside of the same is likewise directed outward. The wings can be detached from their hinges in both their outer and inner positions.
